Abstract
The main goal of the research carried out in this thesis is the modeling of wind
turbines integrated into Medium voltage electrical networks. The considered technology is
based on cascaded doubly fed induction generator (CDFIG). The system employs two
cascaded induction machines to eliminate the brushes and copper rings in the traditional
DFIG. In this case, Cascaded induction generators require lower maintenance.
In CDFIG both stators of connected machines are accessible. The control strategy for flexible
power flow control is developed. The independent control of the active and reactive power
flows is achieved by means of inverter, well attended a linear regulating by regulators PI. We
are used the technique of vector-control by classical field oriented and the Control by a
variable structure regulator (sliding mode).MATLAB software for a simulation of CDFIG
investigation.
